I think you did the right thing covering "$22k-$27k". Some multipliers for that range are pretty high, like 16.22 for "$22,001 - $22,500", for example, while there is a good chance for BTC to end up there on the 31st of December.
Yeah, that's the sweet spot I am waiting for. If bitcoin lands exactly in this range then I will be getting some nice profits.
I used to play Multiple BTC on freebitco.in and recently lost around 0.001 BTC. If I win the bet in this range then I might cover up those losses

In fact, I'm bullish too

, I just bet 1k sats on "$12,001 - $13,000" because the outcome odds, 344.74, were too attractive to not to not put at least something on this range. Same goes for "$15,001 - $15,500", with odds 196.40.
That's a nice strategy. Until your profits cover the total amount in the bets placed you are good to go. But if the profits is less than total amount in bets then that wouldn't be a good strategy.
Let's hope for the best. Anyway, these were some nice odds this time.
